SPECIFICATION forining part of Letters Patent No. 644,836, dated March 6, 1900.

' Application filed June 30,1899. Serial No. 722,374. (No model.)

To all whom it may concern.-

Be it known that we, FRANK H. SWANN and DANIEL F. BROWN, citizens of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in School-Desks; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in a combined school desk and seat; and it consists in the novel arrangement, construction, and combination of parts, as will be more fully hereinafter described, and set forth in the claims.

The object of this invention is to construct a desk and seat combined, each of which may be adjusted to any desired height required, according to the size of the scholar.

Referring to the drawings,'Figure 1 is a perspective view of our invention, showing its complete construction. Fig. 2 is a vertical sectional view of one of the sides, showing how it is mounted in the base and how the backrest is carried. Fig. 3 is a horizontal sectional view taken on the line a a of Fig. 2. Fig. 4: is a horizontal sectional view of the side, taken on the line b b of Fig. 2. Fig. 5 is a perspec tive view of one of the pins used to hold said desk and seat in their adjusted positions.

In the drawings in the construction of the device, as shown, we provide a base 1 to each of the sides 2, in which they are held and supported to the floor. The base 1 is provided with two mortises 3 and 4:,in which are adapted to be placed bars 5 and 6, each of which is provided in one edge with a plurality of depressions 7, which are used to support said bars in their adjusted positions. Through the base 1 are formed two transverse apertures 8, intersecting the walls of the mortises and through which are passed round pins 9, provided with thumb-pieces 10, by which they may be turned, and in their sides with depressions 11, which are of the same depth as the thickness of the bars 5 and 6. When either of said bars is to be adjusted, said pin is turned then allow the bar to be moved up or down. To fasten the same at the desired height, said pin is turned to bring the depression 11 in a horizontal plane,'thus fitting into the depressions 7 and locking said bar in its adjusted position. The bar 6 is provided at its top with a pivoted arm 12, on which is mounted the seat13. The bar 5 is provided at its top with a desk-top 1 1 and a shelf 15, made of gauze or wire-netting, secured to two rods 16, making said netting stiff, and designed to allow the dust and dirt which accumulates in schoolrooms to fall through and keep said shelf clean. Said shelf is held between two guidestrips 17, secured to the inner surface of said side, acting as a guide; To the sides are also secured guide-strips 18, provided with a plurality of apertures 20, in which is placed a pin 21, hereinafter described. the purpose of allowing an L-shaped frame or casting 22 to fit thereover and to which is secured a back-rest 23. This is for the purpose of allowing the back-rest to be adjusted up or down to suit the back of the scholar'on the seat in front. This is done by the use of the pin 21, which passes through the L-shaped frame or casting and into the apertures 20. In order to put the shelf 15 in position, it is placed between the sides before they are secured together and the rods 16 are passed into apertures formed in the desk sides for the purpose. When this is done, the sides are fastened together by placing the top and front thereon. Thus it holds said shelf in firm position. The apertures 7 may be placed on either side of the bars 5 and 6, according to the desire of the manufacturer, and will'work just as well.

Having fully described our invention, what we claim is- 1. In a piece of school furniture, the combination with two upright bars and means for adjusting them vertically, and guide-strips secured to said bars and provided with a plurality of apertures; of a seat-back, L-shaped castings at the ends of the back fitting loosely over said guides, and pins removably passing through the castings and taking into certain of said apertures, as and for the purpose set forth.

2. In a school-desk, in combination with two upright bars 5 and supports therefor, and

7b This strip is for guide-strips 18 attached thereto and provided I In testimony whereof we affix our signawith apertures 20; of L-shaped castings 22 fitting over said strips, a back-rest 23 attached to the two castings, and pins 21 passing through said castings and removably enter- Witnesses:
